The Nikon D90 is an outstanding middle-range DSLR camera. Here are some of the most important Nikon D90 accessories:

The 18-200mm f/3.5-5.6 G ED-IF AF-S VR DX Zoom-Nikkor Lens is a great lens for your Nikon D90. Get the Nikkor 17-55mm f/2.8G AF-S if you prefer high end lenses. For wide angle lens, the Tokina AF 12-24mm f/4 AT-X Pro DX (IF) is a great buy.

For your flash, go for the Speedlight SB-600, a compact flash with striking functionality. The easy-to-view LCD with six buttons makes the operation of the external flash simpler. Each of these backlit buttons is easy to understand.

For the filters, go for circular polarizers, which add flavor to the images. These filters cut the polarized light that hits on the lenses. These filters can remove unwanted reflections introduced by water or glass or other non-metallic surfaces.

The Nikon EN-EL3e Rechargeable Li-Ion Battery is one most important Nikon D90 accessories. You can ensure the best rechargeable battery life; use the usual complete charge of the battery prior to recharging it. A newly charged extra battery makes this possible, giving you nonstop shooting.

What are the best SDHC/SD memory cards for your Nikon D90? Consider getting Kingston, SanDisk, or Lexar. Ideally, get 2 8G cards for a better HD video recording.

The CF-D80 Semi-Soft Case by Nikon is a very nice bag for the Nikon D90. It feels and looks like real, soft glove leather and the price is reasonable. You might want to get the nice Lowepro Slingshot 200 All Weather Backpack if you prefer a backpack, but get the Lowepro Rezo 170AW if you are looking for a good shoulder bag.

For sturdy tripods, buy the Manfrotto 322RC2 or the Manfrotto 190XPROB 3 Section Aluminum Pro Tripod. Both receive outstanding reviews among consumers at Amazon. They suit your Nikon D90.

The Wireless Remote Control ML-L3 works best for your Nikon D90. This slim wireless remote control directly triggers shutter without disturbing the camera. The ML-L3 is ideal for subjects that are difficult to approach or for reducing the vibrations.
